On the structure of the X(3872): lessons from high-multiplicity pp collisions


  • Angelo ESPOSITO

Primary authors


In this talk I will discuss what lessons can be learned about the structure of the famous X(3872) from the study of its yield in high-multiplicity pp collisions. In particular, I will comment on some recent data by the LHCb collaboration, and how well they are reproduced under the assumption of a compact tetraquark state or a loosely bound molecule.
